Naruto: They Have Systems

Uchiha Mikoto was surprised, too. She hadn't expected Kushina to be so fast at her age.

In the blink of an eye, Kushina's fist was in front of Uchiha Mikoto's face. Mikoto seemed unable to defend herself and took the punch head-on.

Bang!

Uchiha Mikoto instantly turned into a log and reappeared behind Kushina.

What a skillful Substitution Technique. This Uchiha Mikoto must be strong.

Tsunade had expected an ordinary fight between two Genin, but their overall strength seemed to be on the level of Chunin.

"Impressive speed. You're stronger than I thought."

Uchiha Mikoto flicked her wrist. With a sharp swish, a kunai shot toward Kushina.

"That's what I've been telling you! I'm strong, so you'd better be careful, Mikoto!"

Kushina's tone was light, but she hadn't let her guard down. Mikoto's hand seals for the Substitution Technique had been so fast that even Kushina's swift attack had come a beat too late.

Her gaze sharpened, and she darted sideways.

The kunai flew past Kushina and sailed behind her.

As soon as she dodged it, Kushina charged at Uchiha Mikoto again.

To Mikoto's surprise, Kushina's punch carried tremendous force—far more than a girl her age should have been able to muster.

She hurriedly retreated, putting some distance between them.

"You're so strong. Are you a taijutsu specialist?"

Mikoto watched Kushina prepare to attack again and murmured to herself.

"Kushina, watch out."

Mikoto gave her a warning, then rapidly formed hand seals.

When she finished, she brought her right hand to her mouth, fingers pressed together with a gap in the middle. Her stomach swelled slightly, then contracted, and fierce flames burst from her mouth.

"Fire Release: Great Fireball Technique!"

Roaring flames surged
